Hours after a powerful blast near President Pervez Musharraf's residence, two rockets were today found in the vicinity of the Parliament House here - close to a place where the Pakistani President was to address a meeting.Army personnel cordoned off the area around Parliament House as the rockets were defused, loaded on trucks and sent for further investigation, the police said.The discovery of the rockets came ahead of a meeting on the anniversary of last year's major earthquake that struck Kashmir. It was to be addressed by Musharraf at a convention centre located one-and-a-half kilometres from the site.Last night, a powerful blast had occurred in a park near Musharraf's residence in the garrison town of Rawalpindi with a media report saying it could have been caused by a bomb or a missile. Pakistan has claimed that the explosion was not aimed at Musharraf.Police officials said two rockets were found close to the lodges where the members of National Assembly and Senate resided. The lodges were located almost opposite the Parliament building, the President's Office and the Prime Minister's Office in the central Islamabad, which is considered one of the most high security areas.Soon after they were found, over 80 people, mostly labourers working in and around the area, were detained. They were all taken to the nearby police stations for questioning.Officials regarded the discovery of the rockets as a major security breach, coming close on the heels of last night's mysterious blast near Army House in Rawalpindi.
